Researchers report in this week's issue of Nature that they've come up with a way to eliminate a cumbersome and little understood step of rubbing separate layers of plastic in a liquid crystal display (LCD) to align liquid crystals placed in between. The advance could simplify and speed display manufacture, drop costs, and help LCDs fight off emerging competition from new flat displays made with light-emitting plastics.
